This Mighty is pretty mighty when it comes to sound quality and operation. It's so simple to set up and sync; done wirelessly and fast. I love the fact that I can transfer my playlists from Spotify and also listen to podcast. Most importantly, I love the fact that the waterproof model for swimming; it's truly waterproof and I can operate it while swimming without losing stride. In short, I love it!

Overall this is a great little device. The size is perfect. It clips easily to the head band of my goggles and is too small to create any appreciable drag. It is so tiny I can store it in my goggle case with the goggles. The convenience of being able to drag and drop Spotify playlists is more than worth the price. The controls are pretty easy to use, even when it is on the back of my head.

I had been using the Wifzu waterproof pouch, which worked, but it was a pain to use and created drag no matter how I used it. I also did not like putting my expensive smartphone in a pouch and submerging it. So this was a huge upgrade.

Setup of the Mighty was pretty buggy. It took 3 tries to get the firmware to update and more than that to get Spotify to connect. I ended up having to reset it to get it working. Also the Mighty takes 30-40 seconds to boot, longer than my phone or my laptop. The earbuds are not going to impress any audiophiles but they work well enough for me and sound better underwater than in the air (like the Wifzu headphones).

Overall I highly recommend it.

This is great for swimming! I love that I can change the music so easily with Spotify. Way better than the old Mp3 players.
